Plasma display and driving method

Abstract

Provided is a plasma display device and drive method thereof. In a plasma display device, a first transistor is connected between an electrode and a power source supplying a first voltage, and a second transistor is connected to a control terminal of the first transistor. A first gate driver supplies a first control signal to the control terminal of the first transistor and is connected to the control terminal of the first transistor. A second gate driver supplies a second control signal to the second transistor, and is connected to the control terminal of the second transistor. Further, a diode is connected between an output terminal of the second gate driver and the control terminal of the first transistor.

Description

Plasma display and its driving method technical field Embodiments of the present invention relate to a plasma display device and a driving method thereof. Background technique A plasma display panel (PDP) is a flat panel display that displays characters or images using plasma generated by gas discharge. The PDP includes a plurality of discharge electrode pairs and a plurality of address electrodes intersecting the plurality of discharge electrode pairs. The plasma display device divides one frame into a plurality of subfields, each of which has a weighted value of luminance, and displays gray levels by combining the weighted values ​​of subfields that generate a display operation among the plurality of subfields. Light-emitting cells and non-light-emitting cells are selected by address discharge during the address period of each subfield, and an image is actually displayed by performing sustain discharge in the light-emitting cells during the sustain period. A sustain ...
